FTP /TFTP Through upgrade IOS PROCESS

1.2.5.3.2 FTP/TFTP Configuration The configurations of switch as FTP and TFTP clients are almost the same, so the configuration procedures for FTP and TFTP are described together in this manual. 1.2.5.3.2.1 FTP/TFTP Configuration Task List 1. FTP/TFTP client configuration （1） Upload/download the configuration file or system file. （2） For FTP client, server file list can be checked. 2. FTP server configuration （1）Start FTP server （2）Configure FTP login username and password （3）Modify FTP server connection idle time （4）Shut down FTP server 3. TFTP server configuration （1）Start TFTP server （2）Configure TFTP server connection idle time （3）Configure retransmission times before timeout for packets without acknowledgement （4）Shut down TFTP server S4600_Configuration Guide.doc Chapter 1 Basic Management Configuration 1-33 1. FTP/TFTP client configuration （1）FTP/TFTP client upload/download file Command Explanation Admin Mode copy [ascii | binary] FTP/TFTP client upload/download file. （2）For FTP client, server file list can be checked. Admin Mode ftp-dir For FTP client, server file list can be checked. FtpServerUrl format looks like: ftp: //user: password@IPv4|IPv6 Address. 2. FTP server configuration （1）Start FTP server Command Explanation Global Mode ftp-server enable no ftp-server enable Start FTP server, the no command shuts down FTP server and prevents FTP user from logging in. （2）Configure FTP login username and password Command Explanation Global Mode ip ftp username password [0 | 7] no ip ftp username Configure FTP login username and password; this no command will delete the username and password. （3）Modify FTP server connection idle time Command Explanation Global Mode ftp-server timeout Set connection idle time. 3. TFTP server configuration （1）Start TFTP server Command Explanation Global Mode tftp-server enable no tftp-server enable Start TFTP server, the no command shuts down TFTP server and prevents TFTP user from logging in. （2）Modify TFTP server connection idle time Command Explanation Global Mode tftp-server retransmission-timeout Set maximum retransmission time within timeout interval. （3）Modify TFTP server connection retransmission time S4600_Configuration Guide.doc Chapter 1 Basic Management Configuration 1-34 Command Explanation Global Mode tftp-server retransmission-number Set the retransmission time for TFTP server. 1.2.5.3.3 FTP/TFTP Configuration Examples The configuration is same for IPv4 address or IPv6 address. The example only for IPv4 address. Figure 1-16 Download nos.img file as FTP/TFTP client Scenario 1: The switch is used as FTP/TFTP client. The switch connects from one of its ports to a computer, which is a FTP/TFTP server with an IP address of 10.1.1.1; the switch acts as a FTP/TFTP client, the IP address of the switch management VLAN is 10.1.1.2. Download “nos.img” file in the computer to the switch.  FTP ConfigurationC Computer side configuration: Start the FTP server software on the computer and set the username “Switch”, and the password “superuser”. Place the “12_30_nos.img” file to the appropriate FTP server directory on the computer. The configuration procedures of the switch are listed below: Switch(config)#interface vlan 1 Switch(Config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0 Switch(Config-if-Vlan1)#no shut Switch(Config-if-Vlan1)#exit Switch(config)#exit Switch#copy ftp: //Switch:switch@10.1.1.1/12_30_nos.img nos.img With the above commands, the switch will have the “nos.img” file in the computer downloaded to the FLASH.  TFTP ConfigurationC 10.1.1.2 10.1.1.1 S4600_Configuration Guide.doc Chapter 1 Basic Management Configuration 1-35 Computer side configuration: Start TFTP server software on the computer and place the “12_30_nos.img” file to the appropriate TFTP server directory on the computer. The configuration procedures of the switch are listed below: Switch(config)#interface vlan 1 Switch(Config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0 Switch(Config-if-Vlan1)#no shut Switch(Config-if-Vlan1)#exit Switch(config)#exit Switch#copy tftp: //10.1.1.1/12_30_nos.img nos.img Scenario 2: The switch is used as FTP server. The switch operates as the FTP server and connects from one of its ports to a computer, which is a FTP client. Transfer the “nos.img” file in the switch to the computer and save as 12_25_nos.img. The configuration procedures of the switch are listed below: Switch(config)#interface vlan 1 Switch(Config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0 Switch(Config-if-Vlan1)#no shut Switch(Config-if-Vlan1)#exit Switch(config)#ftp-server enable Switch(config)# username Admin password 0 superuser Computer side configuration: Login to the switch with any FTP client software, with the username “Switch” and password “superuser”, use the command “get nos.img 12_25_nos.img” to download “nos.img” file from the switch to the computer. Scenario 3: The switch is used as TFTP server. The switch operates as the TFTP server and connects from one of its ports to a computer, which is a TFTP client. Transfer the “nos.img” file in the switch to the computer. The configuration procedures of the switch are listed below: Switch(config)#interface vlan 1 Switch(Config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0 Switch(Config-if-Vlan1)#no shut Switch(Config-if-Vlan1)#exit Switch(config)#tftp-server enable Computer side configuration: Login to the switch with any TFTP client software, use the “tftp” command to download “nos.img” file from the switch to the computer. Scenario 4: Switch acts as FTP client to view file list on the FTP server. Synchronization conditions: The switch connects to a computer by an Ethernet port, the computer is a FTP server with an IP address of 10.1.1.1; the switch acts as a FTP client, and the IP address of the switch management VLAN1 interface is 10.1.1.2. S4600_Configuration Guide.doc Chapter 1 Basic Management Configuration 1-36 FTP Configuration: PC side: Start the FTP server software on the PC and set the username “Switch”, and the password “superuser”. Switch: Switch(config)#interface vlan 1 Switch(Config-if-Vlan1)#ip address 10.1.1.2 255.255.255.0 Switch(Config-if-Vlan1)#no shut Switch(Config-if-Vlan1)#exit Switch#copy ftp: //Switch: superuser@10.1.1.1 220 Serv-U FTP-Server v2.5 build 6 for WinSock ready… 331 User name okay, need password. 230 User logged in, proceed. 200 PORT Command successful. 150 Opening ASCII mode data connection for /bin/ls. recv total = 480 nos.img nos.rom parsecommandline.cpp position.doc qmdict.zip …(some display omitted here) show.txt snmp.TXT 226 Transfer complete.
